Abstract
A ligature resistant hook for supporting a personal article from a wall or door or other vertical support surface. The hook includes a pivot arm that is biased into a retracted, substantially vertical position and moveable between the retracted position, an over-extended positon and an extended position located between the retracted and over-extended positions. The pivot arm is biased so as to prevent movement of the pivot arm into the over-extended position until exceeding a threshold weight applied to the pivot arm.
Claims18
A retractable and ligature resistant hook for supporting a personal article from a vertical support surface, the hook comprising:
- a mounting plate, the mounting plate defining a rear planar surface for securement against the vertical support surface;
- a pivot arm, the pivot arm being supported by the mounting plate and having a catch defining a terminal end of the pivot arm, the catch being moveable about a pivot axis between a retracted position, an extended position and an over-extended position, the extended position being located between the retracted and over-extended positions;
- and
- a biasing member coupled between the mounting plate and pivot arm and defining a threshold weight, the biasing member biasing the pivot arm into the retracted position, the pivot arm being moveable from the retracted position to the extended position upon application of a weight to the pivot arm up to the threshold weight, the pivot arm being moveable from the extended position to the over-extended position upon application of a weight to the pivot arm in an amount greater than the threshold weight, in the over-extended position the terminal end of the catch being configured to release a personal article supported by the catch.
A retractable hook for supporting a personal article from a vertical support surface, the hook comprising:
- a mounting plate, the mounting plate defining a rear planar surface for securement against the vertical support surface, the mounting plate including a wall plate and a mounting base, the mounting base being fixed relative to the wall plate;
- a pivot arm, the pivot arm being supported by the mounting plate and having a catch defining a terminal end of the pivot arm, the catch being moveable about a pivot axis between a retracted position, an extended position and an over-extended position, the extended position being located between the retracted and over-extended positions;
- and
- a biasing member coupled between the mounting plate and pivot arm and defining a threshold weight, the biasing member biasing the pivot arm into the retracted position, the pivot arm being moveable from the retracted position to the extended position upon application of a weight to the pivot arm up to the threshold weight, the pivot arm being moveable from the extended position to the over-extended position upon application of a weight to the pivot arm in an amount greater than the threshold weight, the catch being configured to release the personal article in the over-extended position.
A ligature resistant, retractable hook for supporting a personal article, the hook being configured for surface-to-surface mounting to a vertical support surface, the hook comprising:
- a mounting plate, the mounting plate being configured for surface-to-surface mounting and having a rear planar surface for securement against the vertical support surface, the mounting plate further including ligature resistant features comprising all upwardly facing exposed surfaces exhibiting an angular orientation of greater than 90 degrees measured from a plane defined by the rear planar surface;
- and
- a pivot arm, the pivot arm being moveably supported by the mounting plate and biased by a spring into a retracted position, the pivot arm being moveable between the retracted position, an over-extended position and an extended position located between the retracted position and the over-extended position, the over-extended position being a position located greater than 90 degrees from the retracted position, the pivot arm including a catch extending from a pivot sleeve, the pivot sleeve defining an axis of rotation for the pivot arm and for movement between the retracted, extended and over-extended positions, in the over-extended position the terminal end of the catch being configured to release a personal article supported by the catch.
